Henry Smith: I did not notice my hon. Friend slink in behind me, but I am grateful for his moral support, Madam Deputy Speaker, even though by your order he is unable to vocalise it.
On my support for sustainable aviation, I was pleased to host and address a new industry alliance, Hydrogen in Aviation, just last night here in Parliament. The alliance is designed to help the UK lead innovation in that field. That would, along with duty-free on arrival, better support our sector. Aviation and our ports are  vital for UK trade and employment. We can do this in a cleaner, smarter way, and duty-free arrivals can play an important part for the sector.
In closing, it is clear that the introduction of arrivals duty-free stores would support economic growth and provide a tiny boost to the recovery of aviation, travel and tourism from the pandemic. This plan would be funded by industry and would be at worst cost-neutral for the Exchequer. It is a low-risk policy that has already proven successful in some 65 countries around the world. There would likely be no impact on domestic high street sales, due to limited market overlap and differing customer behaviours in duty-free stores. By introducing duty-free stores on arrival, the Government can reaffirm their commitment to supporting the aviation, travel and tourism sectors, and the economic prosperity that they afford by providing employment to so many of my constituents, and to communities across the entire country. The policy is also popular with the electorate, so I hope that the Government will act swiftly to achieve this additional Brexit freedom.
